The complementary metal-oxide semiconductor (CMOS) holds the data your ASUS business computer uses to configure the hardware. The basic input/output system (BIOS) -- low-level software programmed to a read-only memory device on the ASUS motherboard -- initializes all components in the computer based on the data it finds in the CMOS. If you or an employee, however, have locked the motherboard via the BIOS but have forgotten the password, you won't be able to perform work on the computer, let alone boot the operating system, unless you clear the CMOS.

1. Shut down the ASUS computer. Unplug the power cable when the computer powers off.

2. Remove all devices connected to the PC. Remove the side panel from the computer case.

3. Set the chassis on its side. While shining a flashlight inside the case, locate the jumpers labeled "CLRTC."

4. Lift up the shunt from pins 1-2. Put the shunt on pins 2-3.

5. Wait at least 10 seconds. Return the shunt to its original position on the CLRTC jumper to clear CMOS on the ASUS motherboard.

Tips

The location of the jumpers will vary depending on the model of motherboard.
